Combining the features of the Heidelberg Retina Angiograph with high speed, ultra high resolution OCT, means that cross sectional images can be simultaneously mapped to any of these modalities: Fluorescein Angiography, Indocyanine Green Angiography, Autofluorescene, Red-Free or Infrared. One device can be used to track the early, middle, or late stages of a disease with patients sitting at a single station.
Fundus autofluorescence is playing an emerging role in detecting and tracking lipofusin concentrations as a potential early indicator of progression of geographic atrophy. Images of early AMD disease can be used alone or mapped cross-sectionally with OCT.
Gold standard Fluorescein Angiography can be used for baseline diagnostic assessment, then followed non-invasively with combined Infrared and OCT imaging. ICG Angiography (alone or simultaneous with FA) allows deep views of the choroidal vasculature and clear images of RAP which has been reported to have important prognostic value. |
